PACKING.

To all whom it may concem:

.Be it known that I, CLEMENT RESTEIN, a citizen of g at Philadelphia, in'the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Packing, of which the following is a specification.

Objects of the present invention are to provide a packing which shall be eificient and durable for packing, for example, pumps, to provide against accidental detachment of the layers of duck by reason of the wear and movement of the piston rod, and to hold the parts of the packing in proper position when it is bent in ring form whereby it can be adjusted and held up to its work throughout a comparatively great length of time without distortion or undue wear.

The nature, characteristic features and scopeof my invention will be more fully understood from the fol lowing description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a view, partly in section and partly in perspective, of a packing embodying features of the invention. Fig. 2, is a view of the under side of'the packing as arranged in Fig. 1. Fig. 3, is a detail sectional view of a part of the packing. Fig. 4, of the packing bent into ring form, and Fig. 5, is a view illustrating a result or distortion avoided by the present invention.

The packing consists of two parts,, a channeled or grooved part 1, that comprises a back 2, and projections 3, and a part 4, fitted into the channel or groove of the part 2. The part 1, consists of superposed layers each of which extends continuously across the back 2, and around the projections 3. These layers may be of duck and rubber or the like. Since these layers extend in the manner. described it is evident that they are not likely to be pulled away or detached by the motion of the piston rod. The part 4, may consist of a braid or plait of fibrous material of which hemp, jute and flax are examples. 5, is a line of stitching or a row of stitches which extend across the projec- Specification of Letters Patent Applicationfiled April 10, 1907.
